To all whom/it may concern:

Be it known that I, EDWARD B. Hess, a citizen of the United States ofAmerica,

county, and State of New York, have invented a' certain new and usefulImprovement in Type-Writing Machines, of which the following is aspecification.

In U. S. Letters Patent No. 950,326, granted to me Feb. 22, 1910, I haveshown card controlling devices analogous to those herein disclosed andupon which the present invention is an improvement;

In the accompanying drawing: Figure 1 is a top plan: Fig. 2, an end viewwith the side plate of the. carriage broken away: Fig. 3, a similarview: Fig. 1, a detail sectional View showing a card holder extending upin front of the platen: Fig. 5, a front elevation: Fig. 6, a frontelevation of the card holder detached: Fig. 7, a, similar View showing amodification: Fig. 8, a detail front elevation of one side of the cardholder showing a part that may be extended across the printing line andswung oi folded down. Fig. 9 is a plan view of what is shown in Fig. 8:Fig. 10 is a front elevation and Fig. 11, a side elevation of c. form ofribbon vibrator that may advantageously be employed. 2

The drawings show onlyso much of the carriage of a front striketypewriting machine of the style known as the Royal Standard as isdeemed necessary to illustrate this invention.

The platen 1 is mounted in the usual carriage end plates 2.

3 is the shift rail and 4 indicates the bearing balls interposed betweenthe bottom rail of the carriage and the shift rail. Or-

dinary rear feed rolls 5 and front feed rolls 6 are indicated as well asthe usual paper table 7 and a paper pan8 extending down under the platenbetween the front and rear feed rolls. On the shift rail is mounted asheet metal card holder, generally designated by 9, and shown as made inone piece. It comprises a foot 10 bolted to the shift rail and anupwardly and forwardly extending portion 11 and an upright portion 12that'is extended laterally on each side and is formed with-laterallyforwardly inclined wings 1.3. Since this card holder shiftsverticallywith the carriage, its relation to the platen is a constantone and its upper"edge, which lies at the base of the carriage. In frontof line of printing, is engraved with a scale 1'1 and is parallel withthe axis of the platen so that it constltutes a straight edge by.

maybe definitely brought to the printing insertion of a letter.Cenpoint, asfor the away-or notched at 15 to trally, it. s cut permitthe passage of the type heads to the printing point. On each side ofthis notch. and suitably adjacent the printing point, is an upwardlyextending trowel-shape part 16 that is concavo convex in the direction.of the length of the platen and curved in the direction of thecircumference of the platen. These parts 16 extend across and above theline of' print. In the central part of the plate forming this cardholder 9, generally below the recess 15, the plate may be cut away asindicated at 17. This does not detract from the strength, reduces itsweight, gives it an ornamental appearance, and providesspace for otherparts, as for instance, a ribbon vibrator. In rear of the card holderthere is shown the usual platen scale 18 which, as is well known. is ormay be adapted to be moved to and from the printing line. ever, thatwith the scale bearing card holder 9 the use of the ordinary platenscale 18 is not essential, except for gaging long lines or scatteredimpressions. 0- operating with the card holder 9 is an upper card orpaper clamp that comprises rod 19 on which, at suitably spacedintervals, are disposed rotatable paper clamping rollers 20. At its endsthis rod is mounted in the front ends of forwardly extending arms 21pivoted upon a transverse rod 22 extending between the side plates ofthe the rod 22, a reaction spring 23 is applied to each arm 21 and hasits lower end connected with the side plate at such point that, innormal position, the spring tends to draw the rollers 20 against thesurface of the platen and, when the arms 21 are swung upwardly andrearwardly until the spring 23 passes the center or rod 22, the reactionof the spring will tend to throw the arms down rearwardly and so holdthem, thereby removing the t0 entirely inoperative position. 'The paperclamping rollers 20 have their forward edges in a vertical line in rearof a parallel line touching the upper ends of the card hold- It will befound in practice, howing part .16 and therefore the rollers are asubstantial distance inrear of the printing surface on the platen. 'Thegeneral purpose of this arrangement is that, as shown in Fig. 2, aninserted sheet, card or envelop 24 may be allowed to pass upwardly fromthe card holder infront of the clamping rollers/29. by reason of thefact that the rearwardly extending card or paper holding parts 16 act inconnection with the front feed rolls 6 to holdthe card orpaper closelyagainst the surface of the platen at the point of printing.

In Figs. 2, 3, and 5,the card holding parts or fingers 16 are shown asintegral with the card holding scale plate 9. A modification of thisarrangement is shown in Figs. 4, 6,

7 8 and 9 which indicate that one or both of the curved card holdingfingers 16. may be pivotally or otherwise movably connected with thecard holding plate- Thus in Figs. 6 and 9, the left hand one of thecurved fingers l6 ispivoted upon a screw bolt 25 and surrounding it andunder its head is a'spring washer 26. .The scale'plate has an angularlydisposed embossed surface 27 againstnwhich the bottom circular part offinger 16 bears.

This gives to the finger, when swung down, an oblique plane of movementthat carries it away from the platen. It will be obvious that the cardholding finger or device 16 may be collapsed by being swung laterally asindicated in Figs. 8 and 9 so as to be removed from in front of theplaten to afio'rd full visibility of the printed matter. With the device16 at the left of the printing point swung downaway from the printingline, as shown in Fig. 8, there will then be left the finger 16 at theright of the printing point extending across the line of print, as shownin Fig. 6, to hold a card or paper against the platen. This finger 16beingintegral with the card holder 9 avoids all rough edges orprojecting parts to interfere with insertion of cards, etc, or theirmovements while being printed, and being at the right of the printingline in no way obstructs the view of the operator, the words as they areprinted being fully exposed for his examination. This arrangement of onefixed guide finger extending across'the line of print at the right ofthe printing point and integral with the. card holder, which is providedwith a scale, are the essential features and constitute the gist of thisinvention.

Fig. 7 -shows both of the members 16' so movably or pivotally connectedwlth the card holding plate .9 as 'to be collapsed or removed from infront of the platen.

Figs. 10 to 11 show an improved form of ribbon vibrator. In generalcontour it is This is rendered possible-- similar to those in common usebeing pro- 'vided with bent over lips 28 that usually embrace and slideup and down upon the stand'-- ard of the ordinary type bar guide locatedin front of theprinting point.- The slots 29,

29, through which the ribbon is tobe threaded are located and formed asusual. The-upper edge of the ribbon vibrator at e'achside is curvedrearwardly as indicated at 30, as is also the downward extending lipthat forms part of the outer, wall of each slot as indicated at 31. Thisconformation of thevi:

brator permits the ready insertion, or

' threading, of the ribbon thereinto. The

line or' surface thereof, either with or with? out the scale plate, isnot claimed herein but is on the contrary part of one or more earlierapplications filed by me Sept. 19, 1912, Ser.

I claim:

1. A card holding device for a typewriting machine comprising a cardholding plate rigidly mounted on to a part of the'machine stationarywith respect to the transverse traverse of the platen and a guide fingerin-. tegral therewith extending upwardly across ,the line of print and,at the right of the printing point, the upper free edge of the cardholding plate beingv just below the line of print, provided with-a scaleand extending a short distance to the left of the print-' ing point,whereby the characters as printed are unobstructed and all thecharacters of each line fullyexposed to view as the'printing of eachline progresses. Y

2. A card holding device fora typewriting machine comprising a card"holding plate rigidly mounted on to a part of the machinestationarywith respect to the transverse traverse of the platen and a guide fin-'ger integral therewith extending upwardly across the line of print andat the rightof the-printing point, the upper free edge of the cardholding plate being just below the line -of print, having an opening forthe printing instrumentality-v to pass therethrough at the left of theguide finger and having 'a scale at each side of said opening,

-whereby the characters as printed are unobstructed and all thecharacters of each linefully exposed to view as the printing of eachline progresses. I
